; fl heinvention" relates to improvements in valve lifters to be nounted in thelwaste out let of baths, lavatories etc. The object of the l invention is to provide for anarrangeinent of the valve lifter by which it is madeiposslble I 7 towithdraw thelatter, at any time and with- 1 out difficulty, from the waste pipe or outlet pipe or outlet always subject to pollution can The invention consists in that linked tothebotto nendof the rod inserted in the waste or overflow tube in such a way is that the lifting arm is susceptible of being Y angularly displaced in .the. plane going throughthe said rod and the waste valveflandf that the joint can be fixed within the bent por- .elementsof the rod gear-(form a knee. This inserted in the overflow tube as a complete :iunit inoperative condition with freely niova .ble joint by any person without special knowL edge, as the lower; lifting arm, freely rock- 5 1 ing when being ins rted us able to'follow thei bottom curvature ofthe overfiow tube on ac.-

After'fthe joint has beenfixed all elements of the same rod gear form a rigid unitand are susceptible of move,

L According to the invention thejoint is fixed y k the handle '16 of, the valve lifter.

I I II I I pposed'to the endofthesleeve $391 of th end 'etthe e fastened to the plate 21 spread out against theinner wall surface of the overflow chan- I nel so that the valve lift is sufficiently prevented from being-pulled out too easily and without intention, apart from the fact that, according to the invention, the valve lifter gear rod cannotbe. withdrawn unless the joint between the rod gear and the lifter arm has been loosened previously.

Thevalve is opened by the knob handle 16 fastened to the top of the sleeve being raised and for fixing the valve in its opened position a slight turn' of the knob handle is sufficient. As according to the invention the whole lifter unit is guided and suspended within the sleeve 15 and thus all parts of the same partake of the lifting movement when the sleeve 15 is being lifted by the knob handle 16, also'thevalve is lifted at the same time; while the rod gear is raised for the purpose of the valve being opened or lowered for the closure of the latter, all parts of the v valve rod gear move in direction parallel to each other.

Thevalve is closed by a further slight turn of the knob handle 16 by which movement the'projections 18 extending from the sleeve 15 are caused to coincide with the grooves 42 arranged within thelifter head shell 18 and toslide down in andguided by these grooves. As the lifter rod gear positively follows the descending movement during the closure, now the valve will'be closed in the waste tube, all partsof'thelifter rod gear likewise moving in directionsparallel to each other. Y I V i v In case the overflow canal is to be cleaned, the joint is loosened by the spindle 9 being pulled out whereupon the valve lifter toto take out the valve in its open positionf whereupon it is readily possible to clean the waste tube as well as the valve itself.

', V The valve is inserted again without any difficulty regardless of whether the valve lifter has been introduced previously 01' is Y mounted afterwards. What I claim asmy invention, and desire to secure by Letters Patent, is

1. A valve lifter for baths, lavatories and V I the like, consisting of a lifting rod arranged within the overflow canal," a lifting arm pivotally linked tothe-bottom end of said liftin rod and susceptible of being fixedto-the sai rod in anangular position by means of a stop member displaceable in the lifting rod.

2. A valve lifter for baths, lavatories and the like, consisting of a lifting rod arranged within the overflow canal, a lifting arm pivotally linked to the bottomend of said lifting rod, a recess arranged'in the joint portion of the lifting arm and a lug displaceable in the lifting rod and susceptible of being slid into the said recess.-

3. A valve lifter for baths, lavatories and the like, consisting of a lifting rod arranged within the overflow canal, a lifting arm pivotally linked to the bottom end of said lifting rod, a recess arranged in the joint portion of the lifting arm and a lug displaceable in the lifting rod and susceptible of being slid into the said recess which lug is represented by a shell adjustable in height and fastened to the bottom end of a spindle guided within the lifting rod. 1

4. A valve lifter for baths, lavatories and the like, consisting of alifting rod arranged within the overflow canal, a lifting arm pivotally linked to the bottom end of said lifting rod, a lug fixing the joint connecting the arm to the rod, a spindle guided within the lifting rod'and extending outwards through the handle of the valve lifter, a sleeve rotatably mounted on the knob of the spindle and a lifter head provided with notches.

In testimony whereof, I have signed my name to this specification at Berlin-Wilmersdorf, Germany, this 3rd day of October, 1929.
